county, Ohio, have invented a newand useful Improvement in Dumping-Cars, of which the followin is a full clear, and exact description, re erence being had to theaccompanging drawin forming part of this speci cation, in w oll-' Figure 1- is a longitudinal side elevation of a dumpin ladle car constructed in accordance wi our invention; Fig. 2 is an end elevation of the same showing the dumping motor end of the car; Fi 3 is a view similar to Fig. 2 showi t e rear end of the car; Fig. 4 is a detail elevation of the dumping-motor operating mechanism on a larger scale; 1 1g. 5 is a. detail sectional elevation showing the cross-head, the cross-head slides and connecting mechanisni, and showing the motor-operating mechanism; Fig. 6 is a detail sectional Fig. 6 is a p an; and Fig. 7 is an elevation. showing details of the arrangement of the pipin and motor operating valves; Fig. 8 is a etail side elevation and Fig. 9 a. sectional end elevation showing a portion of the piping to the dumping motor, the valve for the motor and the valve 0 rating lever and showing the oil pump or supplying lubricant to the motor cylinder, and the. pump actuatin connections to the valve operating lever y which the pump is actuated; Figs. 10 and 11 are detail views of the connection between the valve operating hand lever and the operating valve for the dumping motor.

Our invention relates to dumping cars, more articularly dum ing ladle cars emplayed in handling an tran ortin molten materials such as iron or last mace slag or cinder and which are tipped or tilted when bei emptied of their contents. The main ob ect of our invention is to provide an improved operation and control of the movement in dumping. By the use of our invention a slow dumping movement may be imparted to the ladle throu h a part of the'movement; and then a aster movement me. be imparted to dislodge the scull by strik ng the ladle forcibly on the frameof the car at the end of the stroke.

forms a The apparatus may also be adusted so as to give a fast movement throu the entire dumping operation, where it is dds'ired to ve a. stronger-blow for dislodging sculls.

y the same apparatus the dumping movement 'may be made fast throughout the dumping and return movement's. f

Another feature of our invention pro vides for carrying-out any of these operations while dumping the ladle in either direction.

Another important feature of our invention is the provision'cf a reservoir which may be supplied with fluid under pressure; and by which the dumping operation may be carried out irrespective of the position of the locomotive or other source of war.

A further feature of the invention ice in an improved lubricating system.

In the drawings, 2 represents the ladleor -cinder pot of a cinder car secured in place in the trunnion ri 3 formi part of the trunnions4, 4 by w ich the la la is mounted upon the frame 5 of the car. The trunnions 4 are each provided with-a trunnion gear 6 having teeth meshing with similar gear teeth on the trunnion gear racks 7, 7, forming the trunnion supports which are secured to and form partof thecar body' 6.

One of the trunnion gears 6 is provided with ears or lugs 8 8 to oneor the other of which the link 9 1s detachably secured in tippin the Indie in opposite directions. The at or end of the link 9 is'secured'to the cross-head 10 which is secured toand'is moved by the reciprocatin piston rod'll'in the dumping motor ylin er 12. The crosshead 10 is mounted upon suilble longitudinally extending ways or slides 13; one end of these slides hem secured to the bosses or lugs located on t e motor cylinder 12, the opposite ends being attachedtq the glide support 14 forming part of the car The openings through which the slides 18 extend are each provi ed with a recessed portion 10 which so pocket, gr ase or other lubricant ing supplied 'to these pockets in the cross-heads 10 through the grease cups 10" provided; on

the cross-head for that p A reservoir'or tank 15 ls pr'ovided for storing a supply of fluid pressm-e on'each car, being shown as mounted upon the rear en d fof'the car and this tank is connected by of the pipe 16 with the train-supply pipe 17, the adjoiningends of the pipes 17 onadjaccnt' cars being detachsbly connected together'by means of any desirable flexible connection; The supply ipe 17 is also connected bythe pipe 18 wit the motor cylinder l2,in this way forming a bypass around the storage tank 15 and permitting the motor c linders 12 to bedirectly connected with the fluid pressure supply from the locomotive and enabling the car to be dumped not only by fluidpressure from the reservoir 15 but. also by either air or steam supplied direct.- from the, locomotive or any other source. The; check valve 16? on this pipe '16 permits of a free passage of'fluid pressure into the' tank and revents 'the escape of pressure backwar ly through thesupply pipe when the cars are disconnected irom each other. The tank-15 is also connected by'the pi e 19 through the reducing'valve 20 with t e operating valve 21, by which the dumping motor 12 mapper 15 Med and motor supply pipes 22 and 22* ead .from theoperating valve 21 to the orts locatedon the. opposite 'ends' of the umping ,xnotor cylinder 12.

In order-to obtain this c ange 1n the speed of dumping, the valve 24 upon the dumping linder is connected by means of clever arm2i and link or red 82 with the shaft 83, on which the dogs 84 84 are 2 mounted.

root from the am pump on the locomotive or other source, or by means of steam pressure supplied direct by the locomotive or other source.

In order to roperly lubricate the motor cylinder 12 an insure that the lubricant is regularl supplied, a small pump 88. is mount on the motor end of the car and the pump cylinder is connected .by the supply pipe 89 with an oil reservoir 40, and by the pipe cylinder. The piston of the vpump 1s operatively connected by the yoke 42 with the pro'ection 43 on the operating lever 80 and time the lever 30 is actupump is actuated to force a supp of lubricant from the tank 40 into the motor cylinder 12. The pump 88 may be operated independently o trols the dumping movement.

The advanta of our invention are many,v and wil be appreciated by those skilled in the art.

By rovi on ea car, in which a supply of fluid ressure ismaintained, we'are enabled to ump the cars when the 'cars are disconnected from each other or when located at ints remote toone another, and to dump e ears without connection to an external source of supply. .The capacity of the air ,pump on locomotives is relative] small, and where a by the locomotive, the locomotive is enab to fill all of the storage tanks or reservoirs the operating rod which con-.

dmg a storage tank oi. reservoir 41 with the interior of the motor Lin and supply suflicient air to dump all of these cars simu aneously, as by providing an independent storage tank on each car all of the separate tanks may be filled to their 6 capacity by the locomotive while the train is ing hauled over the tracks between the point or points at which they are loaded and the oint of dumping. The cars can then be um after the locomotive is disconnected om the train and has been removed from the point of dumping. By providing the storage tank on each car, and providing the separate pipe lines and valves to the tank and to the motor from the locomotive the cars may be dumped by fluid pressure in the tank or by fluid pressure supplied directfrom the locomotive or other source. The pressure regulating valve upon each storage reservoir prevents waste 0 the fluid pressure and enables the fluid to be used at any desired pressure.

The system for controlling the speed of dumping is sim 1e and eflicient, and avoids any iability o leaving the exhaust valve open when it is desired to give a slow movement through a part of the dumping operation.

Modifications in the construction and arrangement of the parts may be made without departing from our invention.

The car bod may rotate about a fixed axis instead of rolling or rocking as shown in the drawings, and the term dumping car as used in the claims is intended to cover broadly all t pes of rocking, rolling and tilting cars.
